There's what appears to be a very nice Olivetti Programma 101 up on eBay, with a little over a day to go and no bids. It's in the Netherlands. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=8801280590&sspagename=AD… The Programma 101 was a very advanced programmable calculator, introduced in 1965. Discrete transistors, delay-line memory, magnetic card I/O. I've exchanged a little bit of email with the seller. He says its been in storage for a long time, and a couple of rubber belts inside have turned gooey, but looks to be complete and in otherwise good shape. If you want a little bit of discrete-transistor goodness, I doubt you can find it in any smaller package than this (Ok, so a 9100A/B has both discrete transistors *and* core memory, but the Programma 101 was earlier.) I don't have any relation to the seller, I just decided that I wasn't going to bid on this, so I'd make sure the list saw the listing -- this is a very desirable machine and I figure someone, maybe one of the UK folks, would go for it. --Bill

Apple Disk ][ X-Ray

by grant＠stockly.com

This is my attempt at an "art" x-ray. This image includes the entire range of densities. If I were to penetrate the motor I would blow through the plastic. This is a high resolution x-ray. Zoom into the front label and see if you can read the embossed name plates... What COLOR is this actual drive? The answer is in there! ; ) http://www.stockly.com/images2/061231-Disk_II_Drive-120kv6ma15msDG35SFD.jpg This shot was taken with the drive elevated at an angle by foam so that you would get a 3d feeling and not a flat picture. Let me know if its cool. I may x-ray an entire computer next... : ) Grant

The Univac III (in trailer) is back

by ssj152＠charter.net

Well, the Univac III is back: UNIVAC III Computer (In Storage since 1975), eBay auction Item # 2733726990. This time the starting price is $7,500 and the buy-it-now is $11,000. The URL is: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2733726990&category=1247 OK, somebody, jump right on it! :-) (Not me, I'm into LITTLE computers like PDP-11's and VAXen, with an occasional side dish of 6502 or 8085) Stuart Johnson

Is MSX on topic?

More than a little faster, at least to my recollection. Something like 3 times as fast. 16 bit disk I/O and a CPU with nearly 4 times the transistor count of the 8088. A lot of folks who bought the original 6 MHz PC AT discovered overclocking. While you could find 8 and 9 MHz 8088/8086 systems, neither came close to a 6 MHz AT in terms of performance. And if you were adventuresome and clocked that PC AT at 12 or (I've heard it was done) 20 MHz, the gains were breathtaking--and you had a convenient place to cook lunch. One thing that IBM did that really toasted me back then was messing up on the 8237 DMA controller hookup such that memory-to-memory DMA didn't work. It could have made the whole business of extended memory use a lot simpler. Cheers, Chuck

HP 21MX/F and OS choices (was Lookee what I just got!)

by steerex＠mindspring.com

With that work done, it may be practical to boot your HP over a serial port at a reasonable speed, but loading a large ABS file this way can take a very long time (as things are). I generally don't recommend the serial boot method due to its poor performance. Then again, I think its nothing to throw together a PIC and some I2C eeprom and build little paper tape reader and punch emulators, and I can burn copies of any loader rom you wish. I found that serial booting the system to be the easiest way to get started. I don't recall which one but, one of the loader ROMS will work with the "high speed serial" card and read data off a serial link. There's no handshaking or error correction but, with a short RS232 link, passing data is not a problem. The ABS data format does provide checksum error detection so data errors will be detected. On many occasions, I have loaded HPBASIC and other programs over a serial link with absolutely no problem. The advantage to the serial link is that the only hardware required is a RS232 serial cable. Admittedly, it is not as fast as a parallel link but, who cares ;-) I had to write a PERL script to format the data before passing it to the 1000 but, that was fairly trivial. SeeYa, SteveRob

eBay idiocy

by sellam＠vintagetech.com

I find it necessary to clear up some misconceptions and outright lies that have been posted here about me, and to respond to some of the attacks on my personal character. This will naturally be unnecessarily wordy, so if you don't have the stomach for it then just move on now. First of all, I'm sorry that so many people seem to have taken my message as a personal assault. In re-reading the message, it seems the primary reason some people got upset is because I expressed my speech freely, and I also expressed some rather unflattering truths. My tone was angry, yes, but my anger was directed at eBay primarily (because I hate them), and secondarily at the same old useless bitching about eBay that seems to never end here. I think it's pretty clear that I was looking for constructive feedback and/or criticism. Well, unfortunately I got mostly criticism, and little constructive feedback (I do appreciate the replies >from Jules and Curt). Since I did not single out any individual, I can only imagine that those that took personal offense may well have a guilty conscience(?) Since many people seemed to have missed the point, it is this: many people just like to bitch and gripe for the sake of bitching and griping, and because it's easier than actually going out and changing what you don't like. This is what Patrick and I did in building the Vintage Computer Marketplace. We did this primarily to create a nice alternative to eBay for the trading of vintage computers. It was designed and built specifically with the computer collector in mind. It was our hope that the site would be embraced and utilized by the community, eventually becoming a thriving trading site, and ideally becoming commercially viable to make the effort worthwhile. I am fully prepared to admit that the promotion of the site can be greatly improved, but there's only so many times I can mention it on the list (which I used to do regularly when I was actively subscribed) and there aren't many other ways to promote it. I did hear one good suggestion actually (from Curt in private e-mail), which is to promote it on mainstream sites like craigslist, etc. I like ideas like that. Now, on to the personal assaults (you know I can't let them pass without a rebuke). Tony Duell: > I was taught it was extremely bad Netiquette to ask for help (or > physical items) on a list (or newsgroup) that you did not also > contribute to, and in particular on a list that you didn't subscribe to. > > Somenbody helps you, you repay the community by helping somebody else. > Seems reasonable to me. Tony, before I unsubscribed, I had been continuously subscribed to the list (with the exception of a brief stint after the first VCF when I decided I needed a break) since the list began in 1997. I was one of the charter members. In the time I was subscribed, I contributed hundreds of thousands of words, most of which I (and I'm sure many others) would consider "useful". I helped countless people with questions, both on and off list (and continue to do so). If you can't recall the thousands of messages that I contributed here in your presence then please have your head checked. In short, I think I've earned the right to continue to both contribute and draw from a mailing list that I helped to build, regardless of your petty concepts of "netiquette". I don't feel it should be necessary to toot my own horn, but I can count the number of people to whom I've provided free hardware, software, manuals, etc., often covering shipping costs as well, in the dozens. I'm not going to bother going into the promotion I've given and attention I've attracted for the hobby (for better or worse), without which we might've still just been a small throng of nerds playing with obsolete computers. I've been out on the front pushing this hobby forward for ten years now, something one can't do from the comfort of their parents' basement. You might also recall the many times I privately responded to your regular public laments about not being able to find a job by trying to encourage you to move out to the US (this was during the dot.com boom) where your considerable talents would've been in high demand (you always found some excuse to stay within your comfortable little bubble). > For that reason, I ignore any messages from Sellam now. Well, as long as we're being petty, I tuned out your incessant (and often off-topic) jabbering long before I unsubscribed. Richard: > Wow. Bitterness. No, bitterness would've been me taking down the VCM right after I posted my rant. I'm not bitter at all. Quite the contrary, I'm proud that I actually put in the effort and succeeded in creating venues and tools to let collectors express their appreciation of vintage computers and facilitate their interest in the hobby. I would like to see more people take advantage of those tools, and not just keep re-hashing the same old tired gripes about eBay. Look, eBay is always going to act in the interest of their sellers and that's it. Like I said, they don't give a shit about the buyers as long as they are buying, because their money goes to the sellers, and a cut of that goes to eBay. That's their business model. It's a great business model. I wish I could have 1% of 1% of eBay's business. Whatever, my point, again, is that the complainers are never going to get the satisfaction out of eBay that they desire, because the complainers are mostly buyers, and buyers on eBay are just so many cattle grazing at the trough. I wasn't content with just venting. I had a vision and I implemented it. Patrick and I built and deployed a free alternative to eBay that caters specifically to this community; buyer and seller; hobbyists. But the last step in that project is one that has to be taken by the community: we can't also be expected to fill the Marketplace with stuff too. If enough people turned their bitching into action and resolved to use the VCM on at least, let's say, a quarter of their transactions rather than eBay then the site might eventually grow to the point where critical mass would be reached. The last step has to be taken by the community. If the community is so truly fed up with eBay, why aren't they using the VCM? Oh, because they're still using eBay. I fully understand that eBay has the most eyeballs and therefore the most stuff, and also gets you the most money for your stuff. So if it's more important for you to get top dollar for your stuff then great, eBay is a natural choice. But it's also possible to do very well on the VCM, with a trading partner that you know appreciates this stuff as much as you do and will treat it with the proper care and reverence when packing and shipping it. That $1,200 IMSAI 8080 was a good deal for the buyer (relative to what one might expect to pay on eBay) and it was still a pretty good deal for the seller (plus he didn't have to pay listing fees or commissions; that was good for around 40 bucks). But again, as critical mass is finally reached, with lots of eyeballs at the VCM (thanks to the efforts of the community), the prices at the VCM would start to rise as competition increases. Sellers would be getting good money, buyers would be getting good selection. It's an obvious win-win for the community, something that the community could have taken credit for helping to create. But the community ignored it and just continued to suffer eBay. Lamentably. Finally, the reason eBay nets you top dollar is because of the tricks eBay pulls, like the very one that started this whole brouhaha rolling. eBay's system works in favor of the seller, and in doing so it encourages artificial price inflation. To deny this is folly: it is in eBay's interest to push prices up because that means more commissions for them. I guarantee you that if eBay didn't become the premier place for buying and selling vintage computers (or vintage anything) we wouldn't be talking about $2,000 Altairs and IMSAI's (I still insist those values are inflated, though not as much as they used to be). That's an argument I don't want to get into yet again. I refer you to the CC archives where many (IMHO well-laid) arguments of mine can be found. So if eBay is supplanted as the premier trading place for vintage computers by a venue that has a much more equitable trading mechanism between buyer and seller (i.e. the VCM) prices might naturally deflate. Is this undesirable? Or perhaps this is desirable? Mike Stein: > A rather naive perspective, I think.

If Sellam expects the people here to do all > his advertising and build up users for him so HE can someday cash out he > is dumber then I thought. This is patently ridiculous. First, I'll address your ignorance. I have a 4,500 square foot warehouse filled with around 2,000 computers going back to the 1950s, thousands of peripherals of all kinds, thousands of software packages, thousands of books, tens of thousands of magazines, plus all manner of computer related ephemera and things. This warehouse currently costs me $3,646.20 a month to lease. As you might imagine, I also have other costs, such as insurance, utilities, wages, etc. In short, it costs me a lot of money to store all this stuff. Now, if I was in this for the money, why the hell would I be stupid enough to incur thousands of dollars of expenses every month to store all this stuff for the past 10+ years of my life? Why did I pour all my money into acquiring old computers rather than landscaping my backyard, which to this day I'm embarrased to admit is still a field of weeds? If I was someone only in it for the money, my warehouse would be a rented storage shed and I would've been doing a brisk trade out of it. And if I were so inclined, I'd be driving a Lamborghini by now. But I don't. And do you want to know why? I will tell you. It is the same reason I started the Vintage Computer Festival 10 years ago and have been doing it year after year ever since, in fact growing it to multiple events around the world, with a wash (in terms of cash) to show for it (and that's only if you count expenses and don't take my time into account). It is the same reason I used to charter a bus at my expense at the VCF so that people could take a tour of the nascent Computer Museum History Center (now the Computer History Museum) while they were in town for the VCF and raise its exposure. It's the same reason I actively contributed to this list for nearly nine years, never deleting a single message without first reading it. I do this because I have a passion for vintage computing and a love of computer history. It is what I have done since I was a teenager. It is my life's work. This is why I do it. So hopefully you'll understand why I think your comments are incredibly insulting and demeaning, bordering on libelous, and why I now have nothing but contempt for both of you for ascribing such a shallow motivation to my life's work, especially Teo, who is reading nothing new here. You've questioned my integrity before and I explained to you quite adequately that I am not someone who merely buys low and sells high. If you do this again then you and I will tangle, but in a serious fashion. As for how I am able to afford to keep all this material preserved while earning a living, it's no secret. I've explained it before, and every e-mail message I send out has a link to my business' website which explains my work. Regarding those periodic requests I post to the list? Those are what I call bounties. They are opportunities for hobbyists to make a little money in their hobby, sometimes a lot of money. Among other things, I do consulting for law firms in the field of patent litigation. I perform research to uncover prior art, and then I go out and try to acquire that prior art for my client (the law firm). Am I doing well by it? You bet. And as the many people who've successfully responded to one of my bounties can attest, it can be quite lucrative for them as well. If I was just using the list for my sole personal gain then yeah, I can see how that would be annoying. However, and here I will unashamedly toot my own horn, I'm actually spreading the wealth. Now tell me, what's wrong with that? Now, as for selling computers for profit, I do this very, very rarely. Most of what I provide to my law clients are items on temporary loan from my (or someone else's) collection. In the rare event when I do sell, I only consider profit motives when selling to businesses because I won't feel guilty about adding a considerable mark up. With individuals (i.e. fellow collectors) my primary motivation is doing a fair trade. In many cases I just give stuff away to other collectors for the prospect of a future favor returned (it's a concept I learned from a good friend called "enlightened self-interest"). By the way, the most exotic thing I ever sold from my own collection, an IMSAI 8080 for $3,500 on eBay, was to fund VCF 3.0. The next most exotic thing was an Apple //e. But enough of the self-adulation. I'll be honest and admit that I am exploiting my hobby, which I've managed to make into my work, for money, and as much as I can. It's the only way I can afford to maintain and grow this wonderful archive that I've built. So I do it shamelessly. Al Kossow: > I sent email to Jay asking that Sellam be banned from posting. Wow, Al. If that's how you treat your friends, I'd hate to know what you do to your enemies. Thanks, I'll remember this. Other people posted nasty comments about me, but I'm not responding to you because I consider you irrelevant. I should add that this does not apply to Jay, with whom I am having an off-list conversation. I would like to sincerely thank those that came to my defense. I count all of them as friends. Finally, to respond to Jay's follow-up to my initial posting, nowhere did I insult either Jay or the list, but rather I paraphrased what Patrick Rigney related to me when he decided to leave the list and the computer collecting community altogether. Go back and read my original posting. This thread is representative of the aspects of this community on which Patrick's disgust was rightly founded. Lastly, I am not going to apologize for any particular language that I choose to use. I've addressed this at length before and don't find a need to re-visit the argument, suffice it to say that I believe people who find any kind of words "dirty" because of their sexual connotations suffer from arrested development and need to mature. I'm stating my opinion. If you can't handle it that's your problem. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

HP 2117f cables needed

by g-wright＠att.net

Hi, All of this HP 1000 talk got me going on mine. I have most of the drives, paper tape punch and tape drives and a real nice 2117F. But thats where it stops. No Cables Does anyone have a stash of these. I have no cables and cant seem to find anyone that does. It seems that most of these are offered with out the cables. I would guess they all go to bulhead connectors and are just easier to slip off the connector on the cards. Need these at minimum - Console 12966a - HPIB disk 12821a - HPIB Mag tape 13183 Also Trying to figure out 2 cards HP 12250 60001 and a FDS n612 4256-001 Thanks, Jerry Jerry Wright JLC inc g-wright at att.net

Cool! I'm a pioneer, having collected these things for close to 25 years. Well, I'm not sure I would call it collecting in the normal sense of the word. I want to keep these machines running, useable, and in use. Guess that's why Magica exists (even though she's not powered on right now), along with the other machines at the same site. Johnny
